In 1885 Sächsische Machinenfabrik vorm. Richard Hartmann of Chemnitz, commonly known as Hartmann, built a prototype freight locomotive with the 0-3-0 axle arrangement, based on earlier class V of the state railways of Saxony (Königlich Sächsischen Staatseisenbahnen). It was given service number 736, later 1012, and individual name ‘Känzli’. In 1887 this locomotive was ordered in quantity. First batch, completed in 1890, numbered seventeen examples (1013 through 1029) almost identical with the prototype. Second batch was delivered between 1890 and 1895 by Sigl of Vienna (eleven examples, service numbers 1001 through 1011) and Hartmann (63, 1030 through 1092). These engines featured increased diameter of cylinders, from 460/650 to 480/700. Third batch numbered 72 locomotives, built by Hartmann between 1896 and 1901 (1093 through 1164). From No. 1104 onwards number of flues was reduced from 173 to 167, with the resulting decrease of boiler heating surface from 115.1 to 111.37 sq.m. Diameter of the high-pressure cylinder was increased again, to 500 mm. These engines were initially classed H V C. In 1889 they were re-classed H V V and in 1898 re-classed again, this time V V (pronounced ‘five vee’), wherein second ‘V’ stood for Verbundtriebwerk. Examples up to No. 1045 were given individual names. All these locomotives were coupled with two types of three-axle tenders. Apart from above-mentioned 164 examples, SäSt class V V included one more, built in 1920 and numbered 1000; this locomotive, however, was fitted with completely different and larger boiler with Belpaire-type firebox, originally built against a Turkish order.
Several engines of this type, left by German military railways, were taken over by PKP. LP lists nine, with no assignments of service numbers to individual examples. They represent all three production batches. In 1926 they were classed Th101. The same number is given in the 1927 locomotive types list, issued by the Ministry of Transport. Some sources, including www.de.wikipedia.org and Lokomotiv-Archiv Sachsen (see References), give their number as fourteen. The latter source specifies assignment of Polish service numbers to all fourteen examples, but this is somehow suspicious, as increasing orders of PKP and SäSt numbers simply coincide, just like this is the case with DRG re-numbering. It seems possible that fourteen examples were initially specified, but five were either not taken over at all or withdrawn before 1927. All were written off before 1936. Two German engines were lost during the war and eight went to Belgium (SNCB service numbers within the range from 7726 to 7783). DRG took over 140 examples, classed 536-7, but eleven were written off before formal introduction of the new designation system. Last were withdrawn in 1930 and not a single example has been preserved.
